An upcoming show at Digging Pitt gallery provides proof of concept about the potential power of the Burgh Diaspora network. Pittsburgh Alumni: Twenty Artists from Beyond the Rivers runs from September 14 - November 4, 2006. Digging Pitt curator John Morris started looking in the Fall of 2005 for notable artists who left Pittsburgh. The result of his efforts is the Pittsburgh Alumni show, which displays the talent that once resided in the Burgh.
I won't speak for Mr. Morris, but I can envision artists spreading the good news about Pittsburgh as an ideal spot for relocation. At the very least, these artists demonstrate that living in Pittsburgh is not a sentence of creative isolation, other scenes just a click away.
